I've done fairly extensive searching, but I can't seem to find any recent, in depth analysis of whether a normal user will notice any real performance boost running a crossfire setup in x16 link vs x8.

I ask because I'm building a new system, and although I'm not planning on going xfire initially, I likely will when the 4850 cards go dirt cheap in the far future, and I'm trying to decide if I need to get:

or if I should save some $$$ and just go with

Any info would be greatly appreciated.

Appreciate the reply, but that link is about the results with single cards on various pcie pipeline speeds, not crossfire results.

his link should give you a rough idea on how it would work

there would be a decrease in fps overall, but not enough for you to actually regret it

I went for the Asus board, the gigabyte one was out of stock, and the offer for the $30 off for the mobo/4850 combo was too good to pass up.
